Years ago, between 2012 to maybe 2017 I did a lot of engine dyno testing on BB Mopar V8s on five different motors both race only and street and strip. My point is on one motor for a customer we tested two different intakes, both Indy 400 intakes, a 400-3 with a single Holley 1050 CFM early dominator list #9375 jetted for max power and then switch that intake and carb to an Indy cast dual dominator tunnel ram with two of those 9375 jetted on the single intake, we were monitoring the EGT and ignition timing and spark plugs. That motor gained 30 HP from the single carb and intake to the dual dominator's carbs maxed out:wtf: Those tests were done in Klamath Falls, Oregon on a DTS brand engine dyno that had the latest software upgrades:thumbsup:
